comment ListPlot3D of a set of points in a non-convex region
@rm-rf For a arbitrary point cloud on an unstructured grid we will have to accept the Interpolation::udeg message too! Interpolationorder will be constrained to one.

comment Limit for Matrix expression
To see the limit appearing for random matrices one can try n = 3; Q0= RandomReal[{-100, 100}, {n, n}]; res = NestWhileList[(# + Transpose@Inverse@#)/2 &, Q0, Norm[#1 - #2] > 10^-8 &, 5, 10^4]; limit = Last@res ListAnimate[MatrixPlot[#] & /@ res]
